Middlesex County, Connecticut

Middlesex County stretches along the Connecticut River, right in the state’s midsection. It’s home to Wesleyan University, keeping things youthful in Middletown.
This county has a bit of everything. It has river towns, beach communities, and quiet farming villages. You can take a ride on a steam train or catch a show at the Goodspeed Opera House.
It’s a place that’s holding onto its maritime past while sailing into the future. A slow boat, to say the least. But the boat hasn’t casted an anchor yet.
